Moles of X are 0.925 moles.
A mole is a totally vital unit of dimension that chemists use.The mole, symbol mol, is the unit of amount of substance inside the worldwide device of gadgets. the amount quantity of the substance is a measure of how many simple entities of a given substance are in an item or sample. The mole is described as containing exactly 6.02214076×10²³ primary entities
mass of X2O3 = 4 g
so moles = mass/molar mass
molar mass of X2O3 = 2*X + 48 -
Given, that the mass of X = 2.8g
mass of O = 4 - 2.8 = 1.2g
A mole of O = 1.2g/16 = 0.075 mole
∴ mole of X = 1 - 0.075 = 0.925 moles.

C because the liquid is the pond and the gas is the fog. The water from the pond is changing to gas or fog.
The dense aerosol cloud created caused decreases in the amount of solar radiation that reached the Earths surface.
Here, we need to solve this problem using Ideal gas law ( PV=nRT).
Where –
- P = Pressure in atm
- V = Volume in L
- n = moles
- R = Ideal gas law constant
- T = Temperature in K
<u>Now, according to the question </u>–
- V = 58 L
- P = 2.2 atm
- T = 313 K
- R = 0.0821 atm L/ mol K
<u>Calculation</u> –
